一直搞不清楚反意疑问句的be动词选择
children were really poor,_____?
过去式的话.那什么时候用didn't they呢?
he had a breakfast,_____?
这里又要用什么,什么时候用had't he?
主要就分不清楚be动词到底看哪个.一般是看句子里的动词对把?
怎么有时候又出来助动词了.
答
be动词是不是动词？他是谓语吗？
英语句子中是不是每个句子都必有一个动词？
答
children were really poor,_weren't they_?
he had a breakfast,_didn't he_?
第一句是be 动词，be动词否定直接加not，第二句had是行为动词，也叫实义动词，做否定句时要加助动词，had又是过去时，所以用didn't
答
[children (were) really poor],_weren't they__?你看()里是were(be动词),[]中没有never,hardly,little等这些词,所以反意疑问用 weren't they.若是there (is) {little} water in the glass___?就填is there.因为()是...
答
weren't they? didn't they? 怎么还分不清呢?还有,什么叫be动词?你看来还没弄明白.而我明白.说不清.
